What it is

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev97, the /json/package_order, /json/link_order, and /json/abort_link WebUI JSON endpoints enforce weaker permissions than the core API methods they invoke. This allows authenticated low-privileged users to execute MODIFY operations that should be denied by pyLoad's own permission model. This vulnerability is fixed in 0.5.0b3.dev97.
